NOTE:  A special gasket used between closure plate 
and crankcase controls crankshaft endplay, no 
shimming is required. Do not use RTV sealant in 
place of gasket. 
NOTE: Engines with fi rst generation balance weight: 
Apply grease to outside fl at surfaces of balance 
weight guide shoe. Position guide shoe so solid 
end is toward crankshaft. Make sure guide shoe 
stays in this position during step 2.
1.  Make sure sealing surfaces of crankcase and 
closure plate are clean, dry, and free of any nicks or 
burrs. Install a new closure plate gasket onto 
crankcase. 
2.  Ensure gasket, cover plate, and governor gear 
assembly, have been properly assembled to closure 
plate. Start closure plate onto crankcase. Be sure 
guide shoe (models with First Generation Balance 
Weight), is aligned with guide channel in closure 
plate, and cam shafts and governor gear shaft are 
aligned with their mating bearing surfaces. As 
closure plate is lowered into fi nal position, rotate 
crankshaft slightly to help engage governor gear.
3.  Install screws securing closure plate to crankcase, 
with any clamps for wiring harness and sheathed 
RFI suppression spark plug lead (#5 location, if 
equipped). If wiring harness was separated from 
closure plate, route harness through clamps and slot 
in closure plate. Close clamps to retain harness.
4.  Torque closure plate fasteners to 24.5 N·m 
(216 in. lb.) using sequence shown.
